I get this all the time, you need to open task manager and shut down the following files:
rapimanager.exe
two more files which I cannot remember as I don't sync at work wnsvc or something like that, they're one right after another in the task list start with w***..exe.

Disconnect your device from the usb cable, reconnect and then restart Activecrap manually by double-clicking the icon.

Should reconnect normally after that.
